and now I make a web chat application, where users can send files / photos to other users (same as whatsapp). This application runs normally if it is opened through a browser and can send file or photo

open with android browser

then I made the apk version in appybuilder, using the same component webview, I displayed my web application,

but this time I encountered a problem, which is that I can’t send files / photos through this apk.browse button which usually when clicked will display the option to select the file to be sent not to appear.
